METHOD OF REPAIRING AUTOMOBILE RADIATORS.

No Drawing.

T0 aZZ whom it may concern:

Be it known that I, WVILLIAM L. WVAr/rER, a citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and useful Improvements in Methods of Repairing Automobile Radiators, of which the following is a specification.

This invention relates to the repair of leaky automobile radiators or the like, and he object of the invention is to provide a very simple and inexpensive method whereby automobile radiators may be repaired where the tubes, ducts, or honeycomb portions of the radiator have been damaged by freezing or accident, which method will not loosen any soldered parts of the radiator or otherwise affect them.

The method consists in dipping the radiator into melted sulphur to coat the outside surface of the radiator, the tubes, joints and other parts thereof, using a pan, tank or kettle of sufficient depth to hold the sulphur and permit the dipping of the radiator into the molten sulphur so that the entire outer surface of the radiator or the surface of the parts designed to be repaired may come in contact with the sulphur. When the radiators have been dipped and removed from the pan or kettle, they will be coated with a thin coat of sulphur which will penetrate the seams and close the leaks in the radiator.

l/Vhen it is necessary to coat the radiator on the inside, an oven is to be used in which the temperature is raised a sufficient degree to liquefy or melt the sulphur. It will be understood, however, that the heat of the oven is not to be so high as would cause it to melt the solder in and on the radiator. The temperature is sufiiciently high tomaintain the sulphur in a. melted state and prior to placing the radiator within the oven, the water connections and petcock at the bottom of the radiator are to be closed and the molten sulphur will be poured into the radi-.

ator through an opening in the top thereof until the radiator is full of the melted sulphur. When it is completely filled, the petcock at the bottom of the radiator is opened and the sulphur is drained out. This leaves Specification of Letters Patent.

Patented Feb. '7, 1922.

Serial No. 468,198.

a coating of sulphur on the inside of all of the tubes, as well as all other parts of the radiator, and thoroughly closes any opening, seam or crack through which leakage could occur. The coating of sulphur is, of course,

relatively thin so that it does not in any way obstruct circulation through the radiator.

If, in the process of dipping the radiators, any of the sulphur should go through any of the openings or injured parts of the tubes or the honeycomb parts and thus tend to obstruct the free flow of the water or perfect radiation, the sulphur may be removed by placing the radiator in a hot oven and the sulphur drained out.

It is obvious that this method of repairing radiators is a very simple one and extremely cheap. The cost of repairing the radiator according to this method is about $2, and it is obvious that it will cost no more to repair a radiator that has a large number of leak openings than it will to repair a radiator having only one or two leak openings. The sulphur will penetrate the seams and close all leaks without in any way loosening any soldered parts of the radiator.

If there is any moisture inside of the radiator, a current of hot or cold air may be forced through the radiator to dry it before the sulphur is poured into the radiator.

I claim 1. A method of repairing radiators which consists in applying melted sulphur to the surface of the radiator where the leak opening occurs and allowing a thin coating of the melted sulphur to fill the leak opening.

2. A method of repairing automobile radiators which consists in submerging a part of the radiator to be repaired in molten sulphur and removing the radiator therefrom.

3. A method of repairing leaky automobile radiators which consists in dipping the radiator into a bath of molten sulphur to thereby coat the outside surface of the radiator with sulphur, and then'removing the radiator therefrom.

' 4:. A method of repairing automobile radiators which consists in placing the radi consists in dipping the radiators into a bath of molten sulphur to thereby coat the out side surface of the radiator with sulphur.

In testimony whereof I hereunto afiix my signature.
